18 Claims.

My invention relates to combined calculating and recording machines, andmore particularly to improvements in combined calculating andtypewriting machines of the class known commercially as theElliott'Fisher billing machine.

"By way of explanation, the Elliott Fisher machine, with which myinvention is particularly concerned, is a combined calculating andtypewriting mechanism distinguished, in its typewriting aspect, by downstrike printing mechanism, and keys mounted on a carriage to travel overa subjacent flat platen. Viewed in its computing aspect, it ischaracterized by one or more so-called column registers past which thecarriage travels, a grand totalizer or crossfooter register mounted onand travelling with the carriage, and column and crossfooter registermaster wheels or actuators mounted on the carriage and crossfooterregister frames, respectively, to effect denominational selection intheir related registers incident to the step by step letter spacingtravel of the carriage, and operated in synchronism by the number keysof the machine, to accumulate values in the registers as they areprinted, digit by digit in different columns. Usually the carriage isadapted to travel over the work to both line and letter space theprinted record.

One object is to equip the carriage with two grand totalizers orcrossfooter registers, which may be power-operated either in unison orsingly,

isters with transfer restoring mechanism automatically operative by amotor on the frame, under control "of 'the denominational selectingmechanism of the crossfooter registers.

To the accomplishment of the foregoing and other and subordinateobjects, one-embodiment of my invention has been illustrated in theaccompanying drawings and will now be set forthin deta l, and defined inthe claims'appended hereto.

My invention herein disclosed is conveniently applied to a machine ofthe well-known Elliott Fisher type, having a flat platen and atravelling key carriage, as exemplified, for instance, in my Patent1,904,127, dated April 18, 1933.

As the subject matter of the present invention does not depend for itsnovelty on the main supporting structure, or upon the printing orrecording mechanism, the latter will be but briefly referred to.

A base of the machine, (Figure 1), includes laterally spaced, parallelside bars 2 connected by front, rear and intermediate cross-braces (notshown).

A track frame In is mounted upon and arranged transversely across theside bars 2. The track frame I includes front and rear rails l2 and I3,respectively, connected by side members I4, terminating at their rearends in upright brackets l5, one only of which is shown.

The printing mechanism is of the usual Elliott Fisher type disclosedsubstantially in my U. S. Patent No. 1,251,361, dated December 25, 1917.

This printing mechanism is mounted in a carriage wheels H, the front setonly being shown, travelling on the rails l2 and I3 of the track frameIt) to enable the carriage to advance from left to right in letterspacing direction and return.

A power barrel mounted on the track frame I9, is connected to thetravelling carriage l6 by a tape 2| to advance the carriage in letterspacing direction under control of the usual carriage escapementmechanism (not shown) Mounted on the carriage I6 are down strike typebars 22 operable through connections 23 by the usual alphabet keys 24,value or numeral keys 25, and clear signal keys 26, the respective keylevers 21, 28 and 29 (Figure 2), of which are suitably fulcrumed in thecarriage l6, and nori mally held in their upper positions by the usualsprings (not shown).

The machine embodying my present invention is equipped with twocrossfooter registers, presently to be described, and with two clearsignal keys 26.

The machine is equipped with the usual wellknown ribbon mechanismincluding ribbon spools 3|, (Figure 1), and a color field controllingribbon shift key 34, (Figure 2).

Associated with the letter spacing escapement mechanism of the keycarriage I6 are the usual carriage release and back spacing keys 55 and56, respectively, as shown in my U. S. Letters Patent No. 1,203,519, andNo. 1,203,520, both issued October 31, 1916.

A line finder key 51, (Figure 1), operates line finder mechanism such asshown in my U. S. Letters Patent No. 1,383,096, June 28, 1921.

A carriage tabulator 58 with its key lever 58' and decimal tabulatorkeys 59 with their key levers 59' control a tabulating mechanism such asthat disclosed in my U. S. Letters Patent No. 1,280,697, dated October8, 1928.

The usual space bar 5|, (Figures 1 and 2),

Hi supported by sets of front and rear mounted near the forward ends ofparallel arms 52 suitably pivoted in the carriage, controls theescapement in the customary manner.

COMPUTING MEoHANIsM Column registers Column registers 63, (Figures 1 and2) one for each column of work, are adjustably mounted on a register bar64 secured by screws 64' to the brackets [5 of the track frame HJrearwardly of the carriage H5.

The column registers 63 are of the usual twoway,'reversible typeembodying the usual denominational value indicating wheels 69 visiblethrough sight openings formed in the respective column registers. Thedenominational value indicating wheels 69 are individually andsuccessively driven differentially according to the values of theparticular numeral keys depressed, through a toothed actuator or masterwheel 91.

Each column register is provided with a, twoway transfer and transferrestoring mechanism.

Cross/caters or grand totalizers Crossfooters or grand totalizers 15,16, (Figures 1, 2 and 10), are suitably secured to the right and lefthand sides, respectively, of the carriage IE, to travel therewith. Thesecrossfooters are substantially identical in construction and hence, adescription of one will suflice for both.

The crossfooter main frame 11 includes right and left side plates 18 anda rear plate 79, enclosing a crossfooter register sub-frame, the sidesof which subframe embrace the register per se. The denominational valueindicating wheels 82 are journaled on a shaft 8|, (Figure 10), mountedin the sides 89 of the sub-frame, and are adapted to be driven inopposite directions for addition and subtraction, respectively, bytoothed denominational number wheels, as shown at 83, journaled on ashaft 84 also mounted in the sub-frame. The number wheels 83 drive theircorresponding value-indicating wheels 82 through the intermediate gears84', 83 and 82'. Associated with the number wheels 83 is a twowaytransfer mechanism of the type disclosed in my U. S. Patent No.1,576,961, dated March 16, 1926, which includes a series of transferheads, one of which is shown at 85, mounted to rock upon a fixed shaft86 to either side of a normal central position. Rocking movement of atransfer head is effected initially by a transfer tooth (not shown) onan associated number wheel 83 engaging a trip member 81 on the head, tomove the latter in one direction or the other, at the proper time.Movement of a head 85 is continued in the direction in which it wastripped by actuating mechanism, including an actuator lever 88, a spring89 urging the lever toward the axis of the head, and a link connection96 between the head and actuator lever. The arrangement of each head andits actuating mechanism is such that, in the normal position of theparts, they assume a dead center position providing a toggle lockresisting the urge of the spring 89, in which position they areyieldingly held by a pivoted detent 9| urged by a spring 92 against aroller 93 on one end of the link 90. Combined carrying fingers andlocking dogs 94, tensioned by springs 94, are mounted on each head toexecute a carrying step of movement in carrying or borrowing direction,respectively, upon the next higher number wheel 83, and for yieldingmovement on their heads to facilitate return of the parts to normalposition.

Denomination selecting means for column registers Mounted at the rear ofthecarriage I6, (Figures 1, 2 and 4), between brackets 95 upstandingfrom a carriage top plate 96, is the usual toothed actuator or masterwheel 91' fast upon a master wheel shaft 98 journaled at its oppositeends in said brackets. The master wheel 97 is advanced laterally step bystep with the carriage I6 in the usual manner, well understood in theart, to select the number wheels 69 of the column registers 63 foroperation in denominational correspondence with the orders in whichdigits are printed in the columns.

Denomination selecting mechanism for crossyootcrs Denomination selectionin the crossfooters I5 and I6 is effected in correspondence with theorder of printing by the following means. Each crossfooter I5 and f6includes the usual toothed master wheel 59, (Figure 2), and squaredmaster wheel shaft Iiifi for rotating said master wheel and along whichthe master wheel advances laterally across the number wheels 83 of thecrossfooter register. The master wheel shaft I06 extends between theside walls IS of the crossfooter frame. Associated with each masterwheel 99 is mechanism for advancing said wheel step by step from itsnormal ineffective position one step to the left of the number wheels 83into meshing engagement with each successive number wheel.

The master wheel advancing mechanisms, (Figure 2), each include a masterwheel carriage i-GI movable on guides IQI' and connected by a link 32 toa forwardly extending crank arm m3 fast near the upper end of a verticalmaster wheel advancing shaft I64 journaled in forwardly bent ears It?)on the crossfooter rear plate I9. A rearwardly extending crank arm I86,(Figure 2), fast on said shaft I84 near its lower end, pro'ects througha slot Iil'I in one ofa pair of laterally spaced housing plates I63,arranged across the rear of the carriage and suitably secured to lateralears formed on rearwardly extending lugs I68 of the side walls I8 of thecrossfooters l5 and I5, to travel beneath the column registers 63 withsaid carriage. A pair of longitudinally slidahle coupling bars IE9,(Figures l8 and 19), one of which is associated with each arm id i, aremounted, side by side, between upper and lower series of rollers I If)and between said plates I88. Springs lII anchored to one of ti e fillerblocks iiI' between the ends of the housing plates Hi3, yieldinglyconnect said plates Hi8 and bars I59 to urge the coupling bars iii?) tothe right, as viewed in Figures 18 and 19. A coupling dog i I2 urgedupwardly by a spring I I3, is pivoted on each bar N39 to engage andinterlock with 2, lug II4 on the bottoms of each of the column registers63 when the carriage I5 has advanced the printing point of the mackn'neto within one letter space of a column position on the work. Engagementof a dog with a lug ms arrests movement of its bar H33 relatively to thecarriage, and against the action of its spring Ill. Normally thecoupling dogs lie one behind the other, (Figure 19), adjacent theprinting point of the machine. Thegcorresponding crank arms I86 andcoupling bars II!!! are connected by links I55, so that when either barm9 is held stationary, continued advance of the carriage I5 will advancethe appropriate master wheel 99 for proper denominational selection inthe related crossfooter. Projecting studs II6, (Figures 1'7 to20), 0nthe respective dogs II2, enter elongated cam slots III in the respectiveplates I08, the studs cooperating with the cams formed at the ends ofthe slots to uncouple the dogs and release the bars I09 when theprinting point of the machine advances in letter spacing direction pastthe lowest denominational order of the column position, whereupon thesprings III retract the master wheels 99 across their respectivecrossfooter registers, to their normal positions, one step to the leftof the wheel of highest denomination, as will be clear.

The means for advancing the crossfocter master wheels 89 co-incidentallywith the advance of the column register master wheel 91 is fully setforth in the parent application above referred to.

The numeral key controlledsmeans for effecting differential movement ofthe column register and crossfooter master wheels 97 and 99,respectively, need not be herein explained as it is fully set forth inthe parent application, it being sufficient to state that thedifferential mechanism is driven from a general operator shaft I'M.

The shaft I'M, (Figures 1, 2, 4 and 5), extends across the carriage I5and through bushings I15, (Figure 4), in the vertical brackets 95, theends of the shaft I'M terminating adjacent the inner side plates iii ofthe crossfooters "i5 and i6 (Figure 1) The ends of the general operatorshaft I'M are journaled in sleeves Iii: rotatably mounted inanti-friction bearings H5 supported in brackets i'l'l' rising from thecarriage top plate 96.

The general operator shaft I74 is driven in clockwise direction, lookingfrom the right, by an electric motor H8 (Figure 5), suitably connectedat the rear of the machine to the rear face of the rail E3 of the trackframe i6. A Worm I82 and a worm gear I83 connect the armature shaft I85of the motor to a short transmission shaft 5% journaled in thetransmission casing I19.

A main drive shaft I81 extending transversely of the machine at the rearthereof is journaled one end in a bearing its in the transmission casingI759, the inner end of the main drive shaft carrying a bevel gear I89fast thereon within the transmission casing I19, and in mesh with aco-acting bevel gear H89 fast on the adjacent end of the shorttransmission shaft 86. The oppcsite end of the main drive shaft l8lextends through an opening in the left hand vertical bracket is andthrough a bearing sleeve Ifli! into a gear housing lei, which may beintegral with the hearing sleeve constituting part of a bracket securedto the outer face of the vertical bracket I5. A cover plate IBI closesthe outer end of the gear housing.

Above the main drive shaft It? is a transversely extending squaredspline shaft I93 having a bearing (not shown) at its right hand end inthe adjacent bracket 15. The left hand end of the spline shaft I93projects through a bea ing into the gear housing IEI, such left hand endbeing equipped with a gear I96 to which power is transmitted from themain drive shaft through a gear I95 fast thereon and in train with theintermediate gears i-fil, journaled on stub-shafts in the housing.

An. inclined jack shaft 5%, is operatively connected at its upper end tothe general operator shaft lid by beveled gears IE9 and 28%, fast onsaid shafts, respectively, the elongated sleeve of the beveled gear I39fast on the jack shaft, being journaled for support in theabove-mentioned bushing I15 projecting from the left hand bracket 35,the elongated hub of the left hand bushing I15 being provided with abearing 2M arranged at right angles to horizontal shaft I14, for thispurpose.

The spline shaft I93 is operatively connected to the lower end of thejack shaft I93 by beveled gears 232 and 233 on said shafts,respectively, mounted in an angular bearing member 234 similar to thebearing member I15, suitably secured to the carriage I6 and slidablealong the spline shaft I33 so the gears 232, 233 can move axially of theshaft I33 with the shaft I14 and the carriage Iii, as the latteradvances in letter spacing direction and return.

MAIN DRIVE CONTROL A motor control bail 235 (Figures 1, 2, 4 and 7-9),embraces the upstanding brackets 95, the arms of the bail being pivotedto studs 201 projecting outwardly from the sides of the brackets, asshown in Figures 2 and 4. A spring 238 connected to one arm of the bail233 and anchored to the adjoining bracket 95 tends to hold the bail atthe limit of its upward movement. Adjacent one side of the bail 203 is acircuit making and breaking device in the form of fixed and movablecontact members 239 and 2&6 (Figures 6-9, both inclusive), one of whichmembers is secured by screws 233', and the other of which members issecured by a binding post 2H1 to an insulator block iii! supported byand spaced apart from the right band bracket 95, (Figure 2), bylaterally extending bolts 2 I2 and insulator sleeves 2 I3. The movablecontact member ZIO is arranged to overlie the fixed member 239 and theadjacent arm of the motor control bail 236, (Figures '7 and 9), suchmovable contact'member being urged downwardly toward contacting positionby a spring 2% coiled about the extended end of the binding post 213.The spring 2M is tensioned by fastening one end to a screw 214', theopposite end of the spring bearing against the contact 2H1 to urge thelatter against the contact 233 and close the circuit. The spring 208 ofthe control bail 236 is stronger than the contact spring 214, so thatthe control bail 286 normally holds the movable contact member Ziil outof contacting position, but depression of the bail 235 enables thespring 2M to close the circuit whereby to energize the motor.

A pair of stationary contacts or bus-bars Eli are imbedded in parallelrelation in an insulating strip (not shown) secured to the front face ofthe rear rail I 3 of the track frame I for engagement by a pair ofsuitably insulated brushes 2I5,

(Figure 6), mounted on the carriage IE to travel therewith. Each ofthese brushes ZI maintains wiping engagement with the lower edge of itsrespective bus-bar 2I3. A lead 22I connects one bus-bar 2E3 to one sideof the motor I18. Leads 223 and 223 connect the other side of the motorand the remaining bus-bar 2I3, respectively, with a plug socket forreceiving the usual power leads 223. The fixed and movable contactmembers 233 and 2H! of the circuit making and break- 1 ing device areeach connected to one of the brushes 315, the one by a wire 221, and theother by a wire 228, so that the circuit may be made or broken throughthe motor through contact members 233 and ZIO.

AUTOMATIC Cnossroorna RESTORING MECHANISM Returning now to thecrossfooters or grand totalizers 15 and 13, reference to Figures 10 and11 discloses a rocking transfer restoring bail 315 pivoted'at 314 to theinner faces of the walls 39 of the sub-frame of a grand tctalizer, itbeing understood that each crossfooter is similarly equipped. Thetransfer restoring bail 315 includes a cross rod 316 overlying the outerfree ends of the actuator levers 38 of the denominational transfermechanisms of its respective totalizer. The bail normally lies apartfrom the free ends of the actuator levers to avoid interferenee with thelevers during carrying operations. Depression of the bail will engageand return any tripped transfer lever 28 and its related transfer headto its normal cocked position.

The particular novel feature constituting the invention to which thisapplication is directed, will now be set forth. The transfer restoringbails 315 are power-operated by the general operator shaft I14 throughdriving connections between said shaft and said bails, as follows:

Associated with each transfer restoring bail 315 is a bail rocker,including a rock shaft 318 journalled in the crossfooter plates andsubframe 18 and 83, respectively, bail rocking arms 319 fast on saidshaft 318, and links 383 connecting said arms 319 and the cross rod 313of the transfer restoring bail.

We have seen that the ends of the general operator shaft I14 arejournaled in sleeves I16, (Figure 4), supported for rotation in thebrackets I11. The rotatable sleeves I16 form part of pitman connectionsbetween opposite ends of the general operator shaft I14 and the bailrockers 318-388 of the crossfooters 15 and 16, respectively. Each pitmanconnection includes a pitman rod 38L (Figures 4, 5 and 11), the upperend of which is eccentrically connected at 311 to the outer disklikeface of its sleeve I16, the lower end of the pitman being connected to acrank 332 fast on the rock shaft 318 of the related crossfooter, so thata single revolution of the sleeve I15 will depress the transferrestoring bails 315 to effect a transfer restoring operation and thenreturn said bails to their home positions. A slot 383 in said pitman rod38I receiving a stud 384 on the crank 382, provides a lost motionconnection between the pitman rod 38I and crank 382, permitting reboundof the rocker 318, 319 and restoring bail 315 under the quick drive ofthe general operator shaft I14 as a safety provision against breakage,said slot being open for quick detachment of the pitman rod 38L A spring335 having its ends connected to the rod 38I and crank 382, as at 336and 331, respectively, retains the rod 33I operatively connected withits crank.

Associated with each sleeve I16 is a single revolution,transfer-restoring clutch, (Figures 2, 4, 5 and 12 to 14), including aclutch dog 388 and spring 389 mounted in a housing 430 journaled on thegeneral operator shaft I 14, and forming a part of said sleeve, aratchet wheel 43! fast on the general operator shaft I13, and a rocking,clutch-tripping arm 332. A notched detent lever 4533, (Figures 2 and 3),tensioned by a spring 434 engages a detent tooth 485 on the housing 490to prevent backlash in the crossfooter transfer-restoring mechanism.

The housings 430 and the sleeves I16 are connected by interlocking lugs4%, (Figures 4, 5, 12 and 13), for convenience in assembling anddisassembling the construction. Operation of the transfer restoringclutches and of the detent levers 433 is readily understood. The tail ofthe clutch dog 383 pivoted within the rotatable pawl housing 400,projects through a slot in the periphery of the-housing for normalengagement by the hooked; clutched-tripping arm 402,

The clutch-tripping arms 402, (Figures 3, 4 and 12 to 14) are fast uponindividual rock'shafts 4-tl'mounted' in suitably secured brackets 408andeach is yieldingly held in clutch-disengaging position by a spring459' having its opposite ends connected to the bracket 438 and to acrank arm 4!!! fast on the shaft 407. The transferrestoring clutchesbecome simultaneously effective upon the disengagement of theirrespective clutch-tripping arms 402 from their clutch dogs 388 by theaction of a tripping bar 4! I, (Figures 3., 2, 3, 12 and 13), extendingtransversely of the machine and operatively connected at N2 to theupwardly extending arms of bell cranks 442 and4i3, respectivel pivotedat 474, the remaining arms of the bell cranks being arranged to overliethe crank arms 4I0 on the respective rock shafts 437, so that movementof said tripping bar inthe proper direction will operate through thebell cranks 4I2, M3 and offset crank arms Ma and shafts 407 to rockclutchtripping arms 402 to release the clutch dogs 388, and enable thelatter, under the tension of their springs 389, to engage the ratchetwheels 43!.

A motor control finger M5 is pivoted co-axiallywith one of the bellcrank levers 452, the free end of the finger being arranged to overliethe motor control bail 236. Studs M6 on the bell crank M2 and finger4I5, respectively, and a spring link 4I7 superior to the spring 288 ofthe motor control bail 205, operatively connect the crank H2 and fingerM5 for depression of the bail-206 andconsequent energizing of the motorI78 when the transfer restoring clutches are engaged, and toprovide ayielding safety connection in the event-of obstruction to the operationof said bail.

The tripping bar 4| I is operated to engage the transfer-restoringclutches and to incidentally energize the motor I78, through theabove-described connections, by the denomination selectingmechanism ofthe crossfooters 75 and 76 under controlof the master wheel-advancingmechanism' of either crossfooter. To this end, the 0pposite ends of thetripping bar 4 are provided with extensions 4I8 projecting into thecrossfooters 75 and 76, respectively, and'guided in the side frames 78-thereof foroperation of the bar 4II by the master wheel carriages IOIco-incidentally with the advance of the master wheels 80 to the right ofthe number wheels 83 of lowest order. For operating the bar 4II by themaster wheel carriages lfll, lugs 4I9, (Figures 12 and 13), are providedon the extensions 4I8 with which collide studs 420 which, in the presentinstance, secure the usual indicators 42I to the respective master wheelcarriages IOI. The spring 489- aided by the motor circuit bail-restoringspring-208 returns the rock shaft 407, clutch'tripping arm 402 andtripping bar 41 I, to their normal positions, upon the quick return ofeither or both master wheel carriages IOI to their normal left handpositions one step to the left of the number wheels 83 of highest order,under the influence of the springs III, when the crossfooter'masterwheelpick-up bars I39 are disengaged from the column registers I53, asheretofore explained."

To insure that the sliding trip bar 4, 4I8 shall remain in its righthand, shifted position asuflicient length of time to hold the motorcircuit closed until the general operator shaft I74 has substantiallycompleted a single rotation, there has been provided an automaticlocking mechanism.

This locking mechanism (Figs. 2, 12, 12 12 and 13) includes a latch 425pivotally mounted at 425 on the right hand side frame 78 cf the lefthand crossfooter, at a point behind the sliding control bar M8, 4! I,the latch projecting forwardly with its free end normally lying upon theupper edge of the control bar.

A spring 429 tends to draw the free end of the latch downwardly to causeit to bear upon the upper edge of the control bar 4%8, M I.

The latch is shown in top plan in Figs. 2 and 13; in front elevation inFigs. 12 and 12 and in side elevation in Fig. 12 from which views itwill be seen that the latch lies adjacent the head of the left handeccentric rod or pitman 385, the latch having a lateral car 425extending into the eccentric path of a stud 428 projecting from theadjacent head of the eccentric rod 38L so that the stud 428 may rock thelatch upwardly, as the eccentric approaches .ie end of its cycle oftravel.

Normally, this stud 428 lies above and slightly apart from the ear 426.

The eccentric path of the stud 428 is indicated by the series of smalloverlapping circles in Fig. 12

The upper edge of the sliding bar 4! I, M8 for operating the motorcircuit bail 285 and the crossfooter carry-restoring clutch-disablingpawl 402, is provided with a notch 427 which, when the bar is in itsnormal position, lies about-in line with the right handside frame plate78 of the left hand crossfooter, as indicated in dotted lines in Fig.12, and shown in full lines in Fig. 12 Thus, the notch or recess 427 isnormally positioned to the left of the spring-pressed latch 425, whichrests on an unrecessed portion of the control bar 4I8, 4| I.

The stud 420 on the crossfooter master wheel carriage MI, by shiftingthe sliding trip bar 4| I, M8 to the right, as the carriage passes fromits units to its sub-units position, causes the trip bar to displace theclutch-disabling pawl 402 and depress the motor circuit control bail20L, and positions the notch 427 in register with the spring-pressedlatch 425, which thereupon snaps into the notch to lock the sliding tripbar 4| I, 4 I 8 in effective position against premature return. Themotor circuit control bail 206 is thus iocked in idle position, as,incidentally, is the clutchdisabling pawl.

As the general operator shaft I74 substantially completes a singlerevolution, a stud 428 protruding from the eccentric head at the upperend of thecarry-restoring rod or pitman 38I, collides with the offsetear 426 on the spring pressed latch 4-25 to raise the latch out of thenotch 427, whereupon the spring 400, aided by themotor circuitbail-spring 208, isfree to restore the sliding trip bar M I, M8 andshift the clutch disabling pawl 402 to elfective position to disengagethe clutch dog as the general operator shaft I74- completes itsrotation.

The tripping stud 428 disengages from the car 426' on the latch, as thegeneral operator shaft I74 completes its rotation, whereupon the spring429 draws the latch 425 down to contact theunmutilated edge of the tripbar 4, M8, th'e'notch 427 having been shifted to the'left out ofregister with the latch.

The spring208' also rocks the motor control bail 256 upwardly, causingit to strike the extending lip 2MP of the movable contact 258 and raisethe latter to interrupt the motor circuit.

The disconnection of the latch 25 from the bar iil, M3 with theconsequent interruption of the motor circuit, is arranged to occur justas the main drive shaft H4 is about to complete its full 360 degreecycle, at which time there is no work to be done, and the momentum ofthe parts is sufficient to complete the cycle, during which finalincrement of movement, the clutchdisabling pawl 562 detains the tail ofthe clutch dog 388 to effect disengagement of the dog from its ratchet38!.

Changes may be made in the form and arrangement of the several partsdescribed without departing from the spirit and scope of the invention.
